Heat (thermal) volume expansion of solid body
$$V_{2} = V_{1}\cdot (1+3\cdot \alpha\cdot \Delta_{t})$$
V2 - final volume
V1 - initial volume
α - temperature coefficient of linear expansion (linear expansivity)
Δ_t - temperature change
V1 - initial volume
α - temperature coefficient of linear expansion (linear expansivity)
Δ_t - temperature change
Find
It is known that:
=
